6 1. Computer Aided Design Used in the design of buildings, automobiles, aircraft, watercraft, spacecraft, computers, etc. Wireframe outline: shows the overall shape and internal features of objects.

7 Animations are used in CAD applications Lighting models and surface rendering are used to show the final product

8 Wireframe Outline

9 2. Virtual Reality Environments A user can interact with the objects in a 3D scene. Specialized hardware devices provide 3D viewing effects and allow the user to pick up objects in a scene. Animations are used to train heavy equipment operators or to analyze the effectiveness of various cabin configurations and control placements.

10 Operating a tractor in a virtual-reality environment

11 3. Graphs and Charts Used to summarize financial, statistical, mathematical, scientific, and economic data Examples: bar charts, line graphs, surface graphs, pie charts, etc.

12 4. Computer Art Graphics packages used in both fine art and commercial art. Examples: Lumena, Mathematica, CAD, desktop publishing software, and animation systems. Morphing: one object is transformed into another. Used in TV commercials.

14 Morphing

15 5. Education and Training Graphics are used to generate models of physics, financial, political, social, economic, and other as educational aids. Examples: flight simulators, ships simulators, heavy-equipment operators.

16 Example: A Military Tank Simulator

17 6. Data Visualization Producing graphical representations for scientific, engineering, and medical data sets and processes.

18 Computer-animation study of minimal surfaces

19 7. Entertainment Used in TV productions, motion pictures, and music videos Animations, morphing, and advanced computer-modeling and surface-rendering methods are used here.

20 8. Image Processing Image processing is the modification of interpretation of existing pictures. Some IP applications: improving image quality, analyzing satellite photos of the earth and telescopic recordings of galactic star distributions. Medical applications: picture enhancements in tomography, simulations of surgical operations, Ultrasonic and nuclear medical scanners.
